SPECIFICATION forming part of Letters Patent No. 768,874, dated August30, 1904.

Application filed January 4, 1904.- Serial No. 187,641. (No model.)

To a 1117mm, it ntmy concern:

Be it known that I, CORNELIUS G. BLAoK, of Ipswich, county of Essex,State of Massachusetts, have invented an Improvement in Box-Fasteners,of which the following de scription, in connection with the accompanyingdrawings, is a specification, like characters on the drawingsrepresenting like parts.

It is customary when shipping goods in pasteboard boxes to secure thecovers in place by means of twine or tape, which must be wrapped aboutthe box and tied. A-suhstantial portion of the time required to pack thegoods is consumed in thus fastening on the the covers, and the expensefor twine or tape is an item of considerable importance.

The object of my invention is to provide a simple form of securing meansfor the cover of a rectangular box of cardboard and similar flexiblematerial which will enable the cover to be readily applied and removedand which will hold the cover in place so securely that it will not comeoff with ordinary usage. I accomplish this object by providing at eachcorner of the box, adjacent its upper edge and on the outer sidethereof, a narrow stay of cloth or paper which has a coating of abrasivematerial. the latter creating a frictional engagement between thebox-body at each corner and the cover, holding the cover firmly inplace.

'In the drawings, Figure 1 is a perspective view of a rectangular-shapedbox provided with my invention, a portion of the cover being brokenaway, and Fig. 2 is a horizontal section through the sides of the coverand box.

The box-bod y a is provided at each corner of its outer side and closelyadjacent its upper edge with a stay 6, each stay being made of cloth orpaper having a coating of abrasive material on its outer side, such assand or emery, the inner or uncoated side of each stay being cemented tothe box and extending a short distance in opposite directions from eachcorner. The cover 0 is fitted tightly over these stays onto thebox-body, and as there is a strong frictional engagement between theinner sides of the cover and the stays Z) the cover will be securelyheld in place. The action of the stays, in holding the cover in place isparticularly effective if pressure is applied to the middle portion ofthe inner side of the cover, as the bending of the cover causes itscorner portions to grip the roughened surface of the stays all the moreclosely. Preferably the cover fits tightly over the rough-surfacedstays, yet it will be held in place even if it fits somewhat loosely.The cover is most easily removed by simply pressing the sides of thebox-body inwardly at each side of one of the corners, thus drawing theadjacent corner portions inwardly, as illustrated in Fig. 2, and movingthe holding-stays thereon out of frictional contact with the adjacentcorners of the cover.

With the above-described means the cover is firmly held in place underall ordinary conditions, while it may bereadily removed and replaced.The staysv coated with abrasive material may be easily applied to thebox with an ordinary box-staying machine.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In combination with a rectangular-shaped cardboard box, havinga coverwith edges fitting over the sides of the box, a series of staystripsinterposed between said overlapping parts, one extending about eachcorner of the box, each stay-strip having a coating of abrasive materialsecured to one side thereof, bearing against the surface of oneoverlapping part, and having its opposite side secured to the surface ofthe other overlapping part, whereby a strong frictional engagement isprovided between said parts, substantially as described.

In testimony whereof I have signed my name CORNELIUS Gr. BLACK.
